I’ve used Qualcomm’s Eudora for years and really loved it a lot. I then moved to Mozilla’s Thunderbird as Eudora kept crashing. In the coming weeks a new version of Eudora will be launched which include: a unique technology designed to prevent users from sending emails to clients, bosses or other designated parties accidentally. Additional Eudora 7 features include ultra-fast index searching– up to 20 times quicker than the current Eudora search function– and greater filing and organization capabilities.
You can download Eudora 7 beta and try it for yourself[end post]
